should definitely not plain stop just because they failed to retrieve
the i2c_adapter name, when all the monitored values are otherwise
available.

See:

lm-sensors SVN should work fine:
http://dl.lm-sensors.org/lm-sensors/snapshots/lm-sensors-r4338-20070305.tar.bz2
If not, please report.

We will release it as lm-sensors 2.10.3 soon.
